Abstract

The utility model provides a drum screen which is long in service life and easy to maintain. The drum screen comprises a sealed casing, multistage serially arranged screen drums, screen through discharge hoppers under the multistage screen drums and a support. The screen drums are supported in the casing through rollers and rollways in rotary modes. Exposed gear rings and gear drive mechanisms driving the gearing rings to rotate are arranged on the screen drums. A through spindle is arranged at the centers of the screen drums. Each stage of the screen drums is composed of a plurality of serially connected screen drum sections, and each screen drum section comprises two support elements fixed on the spindle. Each support element comprises a support ring and spokes supporting the support ring on the spindle. A plurality of bayonets are uniformly distributed on the outer rings of the support rings and are through grooves with cross section contours as major arcs and extending axially. Two ends of rebars with outer diameters same to diameters of the bayonets are embedded in the bayonets corresponding to the two support rings of the screen drum sections respectively, and adjacent support elements and a plurality of rebars arranged between the adjacent support elements and forming annular screen faces form a screen drum section.

Description

Drum sieve
Technical field
The utility model belongs to the material sieving technology field, is specifically related to a kind of drum sieve.
Background technology
At present, drum sieve is adopted in thick, fine grain screening in the coke that enters metallurgical coke oven, iron ore, but existing drum sieve exist be easy to damage, the shortcoming of easy care not.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of long service life and drum sieve for ease of maintenaince.
In order to solve the problems of the technologies described above, the technical solution of the utility model is:
a kind of drum sieve, comprise sealed enclosure, the multistage screen drum of arranged in series, screenings discharge bucket and the support of every grade of screen drum below setting, screen drum is supported in casing by roller and raceway revolution, the gear ring that exposes also is set on screen drum and drives the gear driven mechanism that gear ring rotates, the screen drum center has the main shaft that runs through, every grade of screen drum is made of the screen drum joint that more piece is connected in series, every knotter screen shell ring comprises two supporters that are fixed on main shaft, single supporter comprises bracing ring and bracing ring is supported in spoke on main shaft, be evenly equipped with some bayonet sockets on the outer ring of bracing ring, bayonet socket is that cross-sectional outling is the groove that extends vertically of major arc, two of the reinforcing bar that external diameter is identical with the bayonet socket diameter is embedded in respectively in bayonet socket corresponding to these screen drum joint two bracing rings, some reinforcing bars of adjacent two supporters and the annular of the formation between them compass screen surface consist of a knotter screen shell ring, adjacent two knotter screen shell rings share a supporter, the gap of adjacent two reinforcing bars of the screen drum joint that screen drum not at the same level comprises is different.
Above-mentioned drum sieve also comprises vibration body, and this vibration body comprises the annular ring that is fixed on annular compass screen surface, and the guide post that a two is separately fixed on annular ring at relative 2 is set in annular ring, and a free movable slide block type tup is set on guide post.
Above-mentioned drum sieve, the axial length of every knotter screen cylinder are 1m, and vibration body arranges one every 3m.
Above-mentioned drum sieve comprises the two-stage screen drum, and the gap of adjacent two reinforcing bars of coarse fraction screen drum joint is 20mm, and the gap of adjacent two reinforcing bars of dusting cover sub-sieve shell ring is 8mm.
Screen drum is supported in casing by roller and raceway revolution, the gear ring that exposes also is set on screen drum and drives the gear driven mechanism that gear ring rotates, the reinforcing bar that every knotter screen shell ring consists of compass screen surface is fixed on adjacent two supporters by bayonet socket, reinforcing bar and supporter removably connect, if the single steel bar wearing and tearing can not be used, change this root reinforcing bar and get final product, easy to maintenance.Bar diameter is thicker, and is wear-resistant, long service life.In addition, can come rank and the quantity of corresponding adjustment screen drum joint according to thick, the fine grain ratio of processing raw material, applied widely.
Description of drawings
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail:
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of screen drum joint.
